i know how check checkbox-change jquery how can trigger drupal-function then?

you'll want check out form api ajax options. think you'll want define ajax['callback'] function calls field_attach_update.

<?php function my_form_func($form, $form_state) {   $my_checkbox_val = isset($form_state['values']['my_checkbox']) ? $form_state['values']['my_checkbox'] : null;   $form['my_checkbox'] = array(     '#type' => 'checkbox',     '#title' => t('check me'),     '#default_value' => $my_checkbox_val,     '#return_value' => $nid, // assuming working node, entity     '#ajax' => array(       'callback' => 'my_form_field_update_func',       'event' => 'click',     ),   );   return $form; }  function my_form_field_update_func($form, $form_state) {   if (isset($form_state['values']['my_checkbox'])) {     $node = node_load($form_state['values']['my_checkbox']);     field_attach_update('node', $node);   }   return $form['my_checkbox']; } ?>
